To all whom it may concern:

Be it known that i., ARTHUR B. BARNES. e citizen of the United States, sind a, resident of the city of New York, borough of llt/.ianhetten, in the county and State of New York, have invented e. new and improved Lenip Fixture and Socket Constructlon, ci which the itoilowing is a full, clear, and er:- ect description.

This invention relates to e, construction ci isinp fixture end socket, end has for en object the provision of ineens whereby the socket is in e simple end eiiicient nienner connected to end cieniped within the Xtui-e.

Another object resides in the provision of ineens whereby the ineens for operating the switch in the sochet depends 'troni the fire ture in en entirely new end convenient manner.

A further object resides in the revision oi means whereby the support for t e socket within the idxture end the device for cle-inping the parte of the tintero together are ntiiized es a passageway for the switch opersting ineens whereby seid ineens' depends from the fixture in en entirely novel manner.

A stili further object resides in the perticuler construction end arrangement parts which are hereineftei described end claimed end shown in the accompanying drawings.

The invention is illustrated in the drewings, of whichi'iignre 1 is s. side view ot the device end is attached to e suitebie support, such es e. bed, showing the xtiire partly in section.

`iiig. 2 is e partiel sectioned view of the i'ixtnre showing the socket therewithin teken in e. piene at right ongles to the section teken in Fig. 1.

rihe forni ot the invention shown in the drawings is e preferred form, although it is understood that rnoditicetions in the construction end errengement oi the perts end in the character ot the nieterieis used may be adopted without departing jfrom the spirit ot the invention.

The invention in general relates to e iintiire which is mede in two pieces, such es e, cup 1 end e cep 2 within which e socket 3 is to he disposed. This sociret es shown is preterehly oi the poli chain type end hss the usuel pnii chain i extending thereirorn. The dxture is supported by enorm 5 from e weil or brochet rceinber 6. This may he et teched to a well or other suitable support. This bracket or plate 6 is shown provided with a curved clamping plete 7 which adopts the device to be supported or applied to the heed freine of e bed or any sirniiar point of sup ort. rhe circuit wires are .contained in e ce le 8 which is let in at 9 to the erin 5 end connected in the usual manner to the socket 3.

rihe socket 3, the upper end 1() of which is shown in Fig. 1. extends siightly beyondv the opening in the cover 2 end is fastened in the opening' oi the cover 2 by any suitebie ineens, such es cement7 so that the socket and the cover are movehie es one unit. T he oep 2 is provided with depending annuler ring portions l1 which tit over the corresponding portion l2 on the cup i. riihe hottom of the socket is in the usuel manner formed with e screw-threaded bore, and in the construction shown is fitted with e, threaded hollow pipe 13. This pipe extends downwardly from the end of the socket end is, of course, in line with the exis of the socket. This pipe is adapted to pese through en opening such as li in the bottom ofthe cup 1. It may be threaded through such opening or :may pees loosely therethrough.

The lower end of the pipe 13 is to be received in :i threaded bore 1d ot e nipple 16. This nipple is provided with e. smaller bore 17 extending therethrough in tine with the bore of the pipe 13. By threeding the nipple 16 on to the pipe 13, it wiil be observed that the cap 2 wilt-be more ti htiy held on the cup 1 and, conseqnentiy, t e socket wiii he more rmly mounted within the iixture. The pull chain d ispessed through e ieterei opening such es 18 in the pipe 13 sind thence downward through the pipe end the bore 17 to the nipple 16. The pull chain, therefore. extends downwardly from the here in the nipple end this ceuses it vto depend iroin the fixture centrally irornits iowes't point. This dependence of the puii chein permits its operetion so that the pull on the chain issubstentielly coincident with the exis of the socket end. therefore, no interni strains ere placed thereon. Moreover, the dependence of the chain from the contini lower point of the iixture .gives n very pieeeing, neet.` symmetrical eii'ect es contrasted with its dependence from soine point on the side ont the Fixture, es is usually the cese.

it will, therefore, he seen that .l heve provided e, simple and eliicient construction whereby 'the perte of a lixture een be readily disassembled for repair or replacement end yet he simply and firmly held together when in use. ll also provide ineens whereby the switch ectuating member, such es e, pull chain, in extending or depending from the fixture will not nier its symmetrical eppeerence end in this wey the pleasing eect ott the fixture is enhanced While still permitting the ready operation of the switch in the usuel innnner.

What l claim is:

l. An electric light pull-chain socket construction which comprises e tubular member fastened to the lower end of the socket, seid member hef/ing e lateral opening to receive e pull ehe-in associated with the socket whereby the pull chain can extend from the lower end of the tubular inenilier substantie-lly in line with the exis ol" the socket.

2. A lmnp lifiture construction.'havinge pull ehein socket within the lintnre, which comprises e threaded tubular member con nested to lower end of the socket, seid. member having e lateral opening: therein within the fixture, the lower end of the niemloer extending through the hott-om of the fixture, e hollow7 nipple on the outside of the xtnre engaging with the lower end of the tubular member to support the socket within the lixture, the pull cliein of the socket extending through the lateral openlung1 enel down through the nipple whereby it depends centrelly trom the lower linee olf the lessees lixture end substentielly in line with the axis of the socket.

3. A. lmnp fixture/construction involving u pull chein socket within the fixture, which comprises e cap for the iixture to which the socket is fastened, e tubular member counecteol to the lower end of the socket end extending; through the bottoni of the xture end ineens disposed against the bottom o the fixture on the outside thereof to'engage with the tubular member, seid ineens being adjustable to hold the soclret in position vithin the lixture end the cap tightly on the body ortion of the rixture.

il. lomp lixture construction involving the use of o pull chain soclret within the fixture, which comprises e cap, e loody portion on which seid oep is to loe disposed., the socket 1being fastened to the cap portion, e threaded tubular meniher connected to the lower end of the soclret end having n lateral openingd therein within the llXtiire, e hollow nipf le on the outside of the lintnre and engaging with the lower end el the tubular nxeniller which entends through the bottom ol the fixture, seid nipple being edjnstelole to tighten the csp on the loody rtion whereby the end soclet nre held rinidly in plnce, the lnterelopening in the tuidnler' nienilier receiving the pull chain which en tends through the hollow nipple end depende {Ero-ni the fixture substantially in line with the exise fillfllllllt Bl'tllGHT BARNES.
